TBEEBER, F COLLINGSWOOD, NEw JERSEY, ASSIGNOR 'ro TREIIBER DIESEL EN- GINE CORPORATION, or ciuunEN NEW JERSEY, A eoRPoRATIQN OF NEW JERSEY INTERNAL- COMBUSTION-ENGINE STRUGEURE Application filed September 13, 1927. Serial No. 219,256.

It is necessary at times for the purpose of niaklng repairs or for other purposes that Diesel engines shall be disassembled. For

' instance, it may be desired to disassemble or remove the cylinder head, cylinder, piston and connecting rod from the remaining portions of the structure. Heretofore in the dissary to be actuated in the operation of such engines shall be located laterally of or to one side of and at /a relativel great distance from thesaid valves; or if the said cam shaft or other means shallhave been located directly over the said cylinders then, in order to remove or disassemble the latter from the structure it has been necessary firstto remove the said cam shaft orother means.

' It is desirable that the cam shaft or other means which may be employed for actuating cylinder head or heads of Diesel engine structures in order that the valves for controlling the operation-of the engineshall be operated or actuated by the direct action of such cam shaft or other means and that it be unnecessary to remove the same in order to disassemble the engine structure.

Thegeneral object, therefore, of the invention is to providermeans of novel character whereby the location of the valve actuating mechanism for Diesel en 'ne' structures directly above the cylinder eads may be ren-- I therewith water tight joints.

-jacket'members 7 are provided respectively dered feasible and practical.

The invention also has for its object to provide means whereby the essential parts of a Diesel engine may be disassembled by moving the same in directions laterally of the said engine; that is, in directions transversely of the axis. of the enginecylinder.

The invention resides in the novel combination and arrangement of parts as hereinafter described in detail, particularly pointed out in the claims and as illustrated in the drawings in which I have illustrated one form of mechanical embodiment thereof. The in- A 2 vention, however, may be embodied 1n other "forms of construction than that illustrated and various changes in the construction may be made within the scope of the claimswithout departingfrom the said invention or th principle thereof.

In order that the invention may be readily understood and its practical advantages fully appreciated, reference should be had to the accompanying drawings wherein:

Fig. 1 is a view in side elevation of a multi-cylinder Diesel engine structure embodying the invention; i

Fig. 2 is a view in transverse vertical section taken on the line 22 of Fig. 1;

Fig. 3 is a horizontal sectional view taken on the line 3-3 of Fig. 2;

Fig. i is a similar view taken on the line 1-4.- of Fig. 2; and

Fig. 5 is an enlarged view of a fragmentary portion of the structure taken in the plane in which Fig. 2 is taken, the parts being shown show the structuremore I enlarged in order to clearly. y

In the drawings I have shown a crank casing comprising a base 1 and removable side portions 2. The usual crankshaft is indicated at. 3,'to the crank arms of which the lower ends of connecting rods 4 are connected, the upper ends of which are connected respectively to pistons 5 which reciprocate within the cylinder linings 6 mounted within the water jacket members 7. The intermediate portions of these members are spaced from the linings, 6 but the upper and lower end portions. thereof contact with the said linings as "indicated at 8 and 9 and form The water at their upper ends with inwardly projecting flange portions which are provided upon their inner upper edges with grooves 13 of right angular shape in cross section as illustrated, within which outwardly extending square edged flanges 14 at the upper ends of the cylinders 6 are fitted. This relationship is best water chambers 15. The cylinder heads 16 are mounted upon the upper ends of the cylinders and are secured thereto by means of screw bolts 17, the upper ends of which are 1n engagement with the lower sides of the said heads while the lower ends thereof extend through openings 18 in flan es 19 which extend outwardl and laterally rom the upper ends of the acket members 7. The upper ends of the cylinders and the cylinder heads are clamped together by means of nuts upon the lower ends of the bolts 17. Short tubular sections 20 extend between the chambers 15 and the interiors of the cylinder heads 16. These sections are secured in openings inthe inwardly extending flange portions of the members 7 and project upwardly through openings in the bottoms of the cylinder heads For the purpose of insuring that the joints between the pistons and the cylinder heads shall be water tight, I have provided in the edges of the upper ends of the linings 6 annular grooves 21 into which project annular projections or beads 22 which are provided on the lower sides of the bottoms of the cylinder heads. Packing or washer rings 23 are located in the bottoms of the said grooves 21. Packings 25 are provided about the tubular sections 20 in the planes of the" joints between the cylinders and the said cylinder heads. It will be noted that the upper end portionsof the tubular sections 20 fitloosely in the openings in the bottoms of the cylinder heads so that they may be readily with drawn therefrom.

Inthe construction as illustrated I have shown a four cylinder engine structure in which the c linders, cylinder heads, etc. are

supported upon a frame structure comprising upright'tapered columns 30 and 31 of trapezium shape, the-lower ends of which rest upon the upper edges of the opposite sides of the base 1. In the construction as illustrated the columns 30 are located between adjoining engine cylinders while the columns 31 are located outside of and in ad-.

joining relation to the two outermost vcylinders. It will be understood, however, that the number of engine cylinders and columns may be increased as may be'desired.

The opposite adjoining end options ofthe cylinder heads l6-rest upon t 0 upper ends of the said columns. The opposite sides of each of the said cylinder heads are provided with laterall and outwardly extending.

flanges 35. e flanges of adjoining heads are located in side by side parallel relation to each other as shown in Fig. 1 of the drawings and are connected and clamped together by means of nuts and bolts 36. ,The op 'osite ends of each cylinder head are-provide with semi-circular grooves 37 the two semi-circular grooves of adjoining cylinderheads cooperating to 'form a cylindrical openmg as shown in Fig. 3 of-the drawings. The base 1, the columns 30 and 31 and the cylinder heads 16 are bound andtied together by means of vertical rods 38 which extend upwardly through the said base, through the columns and through the cylindrical openings provided by the semi-circular grooves in the adjoining ends of the cylinder heads. In the construction as illustrated the opposite ends of each of these tying or binding rods 38 are screw-threaded for the reception of nuts 40 which clamp against the bottom of the base 1 and against the upper sides of the cylinder heads.

For cooperating with the outer ends of the two outside cylinder heads I have provided plates 41 provided with. grooves (not shown) which cooperate with the grooves in the adjoining ends of the two outermost cylinder heads to provide cylindrical openings through which theoutermost tie rods 38 ext tend.

The. cylinder heads 16 are rigidly secured together by means of the flanges 35 and the bolts and nuts 36 so that together they conthe opposite sides of the base 1, between the vertical columns pgeviously referred to, by means of screws or the like 45. -.The upper ends of the said side portions are connected to the opposite side edges of a flanged cover 46 tends. The opposite edges of the side portions 2 of .each unit are provided with flanges 50 which contact with the adjoining columns and are secured thereto by means of bolts 51. The joints between these side portions and the portions of the structure to which they areconnected are water tight so that the lubricating oil within the crank case chamber cannot escape by leakage therethrough.

The cover plate 46 of each unit is provided at its opposite endswith oppositely extending flanges 52 which are located in contact with \the sides of the adjoining columns and the said flanges are secured to the said columns" by means of removable bolts 54. It may be noted also that the fastening means by which the-side portions 2 are secured in place are removable ,so thatthe said portions may be removed whenever desired.

It will be seen that .by the means as thus far described the component arts of the en.- gine structure are firmly an rigidly bound to ether. 1

he-cylinder head is provided with the usual valve "structures 60 and 61 which as usual are operated or actuated in timed relation to each other as required in the operation of Diesel engine structures. In Fig. 2 I have shown a spray nozzle structure by means I provlded with a central flanged opening 47 through which the cylinder lining 6 exof which liquid fuel is adapted to be supplied to the upper end of the engine cylinder which is shown in longitudinal vertical section in that figure. As will be seen by reference to Fig. 2 the caln shaft is located directly over and above the engine cylinders and the said valve-structures and that it is provided with cams 66 which are adapted to contact with movable parts of the said valve structures to effect operation thereof. The cam shaft is mounted upon brackets 67 which in turn are mounted upon the cylinder heads 16 as shown. One of the said brackets at one end of the structure is provided with a laterally extending arm 68 having an opening in its outer end within which theupper end of a vertical shaft 69 is journaled. The lower end portion of said shaft is journaled in a bearing 70 upon the outer end of the horizontal arm of a bracket 71 secured to the adjoining column 31.- A bevel gear 72 upon one end of the crank shaft 3 is in engagement with a bevel gear 73 upon the lower end of the vertical shaft 69. Rotation of the bevel gear 72 causes rotation of the bevel gear 73 and the shaft 69 upon Which it is mounted. The upper end of the shaft 69 is provided with a bevel gear 75 which engages a bevel gear 7 6 upon the adjoining 'end of the'cam shaft 65 so that the latter is driven from the crank shaft 3. v a

Assuming now that it is desired to disassemble the structure in order to repair portions thereof or to effect renewals, such disassembling may beiefiected by removing one of the side portions 2, which removal may be effected after the removal of the fastening means by which it is secured to thebase 1, the columns, and the cover 46; also by removing the fastening means by which the said cover is secured to adjoining columns and to the upper edge of the side portion 2 which is not to be removed; by removing the nuts from the bolts 17 by which the cylinder is connected with the associated cylinder head; by removing the fastening means by which the flanges 35 of said cylinder head are secured to the corresponding flanges of an adjoining cylinder head; and finally by removing the nuts from theupper and lower ends of such of the tie rods 38 as may be found to be necessary. Such fastening means having been removed and the cylinder comprising the jacket member and lining 6 moved downwardly or axially a sufficient distance from the associatedcylinder head 16 to withdraw the upper end portions of the tubular sections 20 from the openings through the bottom of the said cylinder head and to disengage the flange 19 from the bolts 17 the parts then may be moved laterally as indicated by the dash and dot position thereof as indicated at 80. The connecting rod 4 may be'di'sconnected from the crank arms of 7 thecrank shaft 3 whereupon the cylinder piston and connecting rod may be shifted in a substantially horizontal lateral direction. It is obvious that the cylinder head may also I be moved laterally from underneath the cam shaft 65 and the cams carried thereby.

It will be seen that by thus providing means whereby these parts which have been mentioned may be moved laterally, a structure may be provided in which the cam shaft is located over and directly above the engine cylinders and cylinder heads as shown whereby the valve structures may be operated by cams mounted upon the cam shaft without the necessity of employing intermediate mechanical means or devices.
